1. Remove all of your baby animals2. Select the hand tool, if you use the arrow tool you will harvest your animal and it will not work.
3. Select a baby animal that is ready to harvest and place it FIRST into the nursery. Now you will notice that your nursery is ready to harvest.
4. Now you want to place all of the animals back into the nursery before tending the nursery, or at least 10 foal.
You will be able to now harvest your nursery...but...you will not get a adult horse every time. If you want, you can do this with the horse barn with just a few animals, such as ten horses with the wandering stallion. If you wish to have a better chance in getting grown horses every time, than you are better off placing common foal and calf in the nursery...aka...black pony foal or Holstein calf.
